Specification of Letters Patent.

Patented Dec. ll ll, 192d.

Application filed March 15, 1920.- Serial No. 365,882. i

To all whom it may concern Be it known that I, MARTIN Prinz, a citizen of the United States. residing at Colwich. in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in an Automatic Connecting-Fod-Bearing Take-Up, of which the following is a description, referring to the drawings which accompanying this specification. I

The invention is applicable to connecting rods as generally employed in internal combustion engines having especial reference to an improved means for automatically taking up the bearings to compensate for wear occasioned by engine operation and to promote and secure an even bearing atall-times for the allied members in the acting combination. I

in the drawings, Figure 1 shows a side elevation of my improved connecting rod and the allied members in the assembly. Fig. 2 is a view taken along the line A-A,

F ig. 1 and looking in the direction of the ar-' rows. Fig. dis a view taken along the line B-B Fig. 1 and looking in the direction of the arrows. Fig. 4: shows the bolt as employed inthe combination in Fig. 1.. Fig. 5 illustrates a plan View of the nut employed upon the bolt in the combination in Fig. 1.

Fig. 6 is a sectional side view of the nut taken along the line C-C Fig. 5 and looking in the direction of the arrows. Fig. 7 is a plan view of'the non-frictional washer. Fig. 8 is a sectional side view of the washer seen in Fig. 7, taken along the line D-D and looking in the direction ofthe arrows. Fig. 9 is a modification of the'washer seen in Fig. 7 and enlarged for aclearer understanding of the construction.

Similar numerals of reference indicate corresponding parts throughout all the figures of the drawings.

Referring to the drawings, in Fig. l is shown my improved connecting rod 10 operatively engaging between a wrist pin 11 and a crank of the crank shaft as at 12, in the well understood manner.

In my invention T provide the outer half of each bearing with hingedly connecting portions for the purposes as further outlined and described. The upper portion of the connecting rod 10 forms a semi-cylindrical bearing 13 within which is seen the pin 11.

" Similarly the lower portion of the rod 10 provides a semi-cylindrical bearing 1's for the crank 12. Lugs 15 and 16 are cast integral with the side of the connecting rod 10. The outer wrist pin bearing 13 hinged at 1'? to a portion integral with the lower bearing element 13 is secured and adjusted in the same manner as the bearing 14 hinged at 18 integral with the upper bearing element 14 which will be described.

A lug 19 integral with the bearing 14 and a lug 20 integral with the hinged bearing 14" are each provided witha hole, said holes as in Fig. 1 stand in ali-nement and substan' tially at right angles to the axis'of the hearing. The lugs 19 and 20 are provided with flat inner faces spaced apart at 21 to permit of take up as will be readily understood.

The bolt 22 seen in Fig. l is provided with a head 23, a threaded inner portion 24 and an outer unthreaded extension 25. The nut seen in Figs. 5 and 6 is provided with a hole 27 to receive the end of a spring as later described; the upper portion of said nut being reduced in size to form a cylindrical collar 28. The washer seen in Figs. 7 and 8 is provided with a plurality of holes 29 within each of which is arranged a ball 30, slightly greater in diameter than the thickness of said washer, the washer serving merely as a retainer for theseveral balls for the purposes later disclosed.

In the assembly of the elements seen in Fig. 1, one end of a coiled spring 31 is inserted within a hole 32 in the lug 16, the other end of said spring 31 is then inserted in the hole 27 in the nut'26 with the collar 28 arranged within the spring 31. The washer seen in Fig. 7 is then arranged be tween the upper fiat face of the lug 19 and the base of the nut 26, the balls 30 being then a roller spacer therebetween adapted to eliminate friction in the functioning of the elements as later described.

but not to compensate for further wear;

by turning the nut 28 and the head 23 oi. the rotatable bolt 22 haclrwardly both at the of the ports 14 and 14* is unchanged but tension will i some time, the relative position given to the spring 251, then as Wear occurs in the bearing, the spring 31 will tend to screw the nut on the bolt and take up play in the hearin Similar parts in the upper portion of Fig. 1 function in like manner as Will he readily understood.

Such modifications may be employed 31S lie Within the scope of the appended claims.

Haring fully described my invention what. l. now claim as new and desire to secure h Letters Pa Lent is:

1. A. hearing of the character described comprising a connecting rod carrying hing;- edly connected elements having their free ends tashionet. es lugs provided nithalined holes transversely disposed. to the a. of the hearing; :1 bolt passing" through. said holes hiiving head at one end. a. threaded inner portion and an outer unthreiided extension; a lug integral with the side Oi said connecting rod, 21 hole therein and within which said extension of said boltv is rota tably housed, e. not screwohly ar ringed on. said threaded bolt and a coiled spring around said bolt having one end secured. Within said lest mentioned lug and the other end secured within seid nut. all sul'istantiiilly specified.

2., A hearing of the character described comprising :1 connecting rod carrying hing edly coni'iected elements having their free ends fashioned as lugs provided with alined holes transversely disposed to the axis of the bearing; at bolt passing through said holes having at head at one end cont-acting the outer iug out the coinhiniition, Zithreaded portion and an outer nnthreaded tatahl housed; a nut screwably ar'auged on said threaded bolt. a roller element as a spacer between said nut and the inner lug of said hinged combination; a coiled spring around said bolt having one end secured within said side lug on the connecting rod and the other end secured Within said nut all substantially as specified.

3. ii bearing oi the character described comprising a connecting rod carrying hing edly coi'inected elements having their free ends fashioned as lugs provided with alined holes transrerseiy disposed to the axis of the bearing; a. bolt passing through. said holes having a head at one end contacting the outer lug oi the e nnbination a threaded inner portion and an outer unthreaded cxlzenmon; a lug in 'ral with the site oit paid connecting rod, a hole therein and within which hole said extension of said bolt is rotatabi housed; a nut screwabl arran 'ed on said i .'eiidcd holt a roller element W a. spacer ween said nut and the inner l oi said hinged combination, a
